Infrared Reflectance Spectra of Lead Glasses Corroded in Acid

Infrared reflectance spectra of lead glasses are reported. Changes in the spectra on addition of K2O and Al2O3 to a binary PbO‐SiO2 composition were observed, and comparisons were made between standard specimens and specimens corroded at several temperatures in 10% acetic acid. The leached glasses d...

Description
Summary:Infrared reflectance spectra of lead glasses are reported. Changes in the spectra on addition of K2O and Al2O3 to a binary PbO‐SiO2 composition were observed, and comparisons were made between standard specimens and specimens corroded at several temperatures in 10% acetic acid. The leached glasses developed spectra very similar to that of fused quartz, indicating the formation of a surface silica layer as the corrosion proceeds. Assignments are made to the various spectral features and rationales put forward to explain their changes during leaching.
